One of the major obstacles to molecular analysis of genomic DNA is the immense size of the molecules involved.
The discovery of a special group of bacterial enzymes, called restriction endonucleases (restriction enzymes), which cleave double-stranded DNA (dsDNA) into smaller, more manageable fragments, opened the way for DNA analysis.
Restriction endonuclease hydrolytically cleave polynucleotides internally at specific palindromic sites
They belong to class III hydrolases
Type of restriction endonucleases
Type 1 - Cleave at random sites
Type 2 - cleave at palindromic sites
